i Application filed July ll, 1904. Serial No. 216,056.

T0 all whom it may concern:

Be it knownthatI, HERBERT G. BEEDE, a citizen of theUnited States,residing at Pawtucket. in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inSpinning-Frame Separator Mechanism, of which the following is aspecification.

My invention relates to a separator mechanism for a spinning or twistingframe; and the object of my invention is to improve upon theconstruction of the separator mechanism as ordinarily made.

In the ordinary construction of a separator mechanism the separator-barcarrying the separator-blades has a vertical movement to raise and lowerthe blades and also a traverse movement to move the blades toward andaway from the spindles. The traverse movement of the separator-barbegins at the lowest position of said bar and conti nues until said barreaches its highest position, so that in case of a long traversemovement of the separator-bar the separator-blades thereon will strikeagainst the thread-guide blocks at the top of the traverse of theseparator-bar.

In my improvements the traverse movement of the separator-bar carryingthe separator-blades is not continuous during the vertical movement ofthe separator-bar, but only takes place when said bar is in a positionsubstantially intermediate its lowest and highest position. A movementin a perpendicular plane is communicated to the separator-bar and theseparator-blades thereon when said bar is being raised to its highestposition, so that the separator-blades will pass between thethread-guide blocks, and, further, in the ordinary construction of theseparator mechanism when the separator-blades and the separator-bar areraised by the operator out of their normal operative position to giveready access to the spindles to remove or replace the bobbins or copsthereon they will remain in their raised position until lowered by theoperator. rlhe operator may neglect to lower the separator-blades andseparator-bar, and the frame will operate with the blades in theirinoperative position.

In my improved construction of the separator mechanism I also providemechanism for automatically returning the separatorblades and theseparator-bar after they have been raised by the operator to theirnormal operative position on the starting up of the frame.

My invention consists in certain novel features of construction of myimprovements, as will be hereinafter fully described.

I have only shown in the drawings a detached portion of aspinning-frame,with some parts thereon and my improvements combined therewith,sufficient to enable-those skilled in the art to understand theconstruction and operation of the same.

Referring to the drawings, Figure 1 is a front view of a detachedportion of a spinningframe with my improvements applied thereto. Fig. 2is,on an enlarged scale, a side view of my improvements detached lookingin the direction of arrow a, Fig. 3; and Fig. 3 is a front edge view ofthe parts shown in Fig. 2 looking in the direction of arrow Z), samefigure.

In the accompanying drawings, l is a portion of the stationary frame ofa spinningframe, and 2 is a hanger secured to the lower side thereof.

3 is the spindle-rail supporting the spindies 4, which carry thebobbins. Only one bobbin 5 is shown.

6 is the spinning-ring rail carrying the spinning-rings 7, mountedthereon. An up-anddown motion is communicated to the spinning-ring rail6 through the lifting-rod 8, which has a vertical movement in thebushings 9 and l0. The lower end of the rod 8 has a foot 8 thereon,which rests upon a small wheel 11, mounted in the outer end of thelifting-arm 12, in this instance made in two parts, with the inner partfast at its inner end on a rock shaft 13, supported in the hanger 2. Arocking motion is communicated to the rock-shaft 13 in the ordinary way.

la is the roller-beam carrying the threadguide blocks l5, having thethread-guides 16 secured thereto in the ordinary way for guiding thethread (not shown) as it passes to the traveler (not shown) on thespinning-rings 7.

All of the above parts may be of the ordinary and well-knownconstruction andoperation.

I will now describe my improvements.

IOO

A plate 17,termed a separator-controller, has at its Lipper end a sideextension 17/, which in this instance is permanently bolted to theroller-beam 14. The front vertical edge 17 of the plate 17 which forms aguide to control the traverse movement of the separatorbar, is madeinclined or oiset out oi' a perplate 17.

pendicular plane, in this instance intermediate its upper and lower end,as shown at 17" in Fig. 3. The upper part of the guide edge 17/ extendsin a perpendicular plane and also in this instance the lower part, (seeFig. 3,) so that said parts do not communicate any traverse movement tothe separator-bar, but only a movement in a perpendicular plane. Asecond plate 18 has in this instancev a vertically-extending slot 18 inits upper end and is in this instance adjustably secured by a bolt 19 tothe rear edge of the plate 17. The lower end of the plate 18 has a foot18H thereon, which has a slot or opening therethrough to receive andguide the upper end ot' the rod 20, which extends through said opening.The lower end of the rod 2O is attached to the arm 12, and theup-and-down motion of said arm 12 communicates a vertical up-and-downmotion to the rod 20. Upon the upper end of the rod 2O is adjustablysecured by a bolt 21 a block 22, which has a side extension 22 thereonwhich is cut out or recessed to receive the guide edge 17H on the A stud23 is secured to the block 22 and has pivotally supported thereon abracket 24, the upper part of which has a shouldered projection 24thereon to receive the recessed rear side of the separator-bar 25, (seeFig. 2,) which carries the separator-blades 26, which in this instanceare secured to said bar 25 by screws 27, which pass through holes insaid bar 25 and have nuts 28 on their inner ends.

By means of the pivoted bracket 24 the bar 25, carrying theseparator-blades 26, may be moved from its normal position (shown byfull lines in Fig. 2) to carry the blades 26 into their inoperativeposition, (shown by broken lines at the left in Fig. 2.)

A projection or lug 22l on the block 22 acts as a stop to engage thebar-holder 24 and hold the separator-bar 25 and limit its downwardmovement. (See Fig. 2.)

As the rod 2O is raised and lowered the separatorbar 25 carrying theseparatorblades 26, will be raised and lowered with it, and theengagement of the lug extension 22 with the guide edge 17 on the plate17 will communicate a perpendicular movement and also a traversemovement to said bar 25 and the blades 26 thereon. ment takes place onlywhen the separator-bar 25 is in its intermediate position, or betweenits highest and lowest positions.

From its intermediate position to its highest position the separator-bar25 only has a movement in a perpendicular plane.

The traverse movei I will now describe the other parts of myimprovements.

On a bolt 29, secured in this instance to the upper end of the plate 17and extending out therefrom, is pivotally mounted the hub 30 of a lever30, which has an extended curved free end 30. In its normal position thelever 30 hangs down by gravity and rests against a stop 31 on the plate17 and in the path or' the separator-blade 26 when said blade is in itsraised backward position, as shown by broken lines at the left in Fig.2.

WVhen the bar 25, carrying the blades 26, is raised in the operation ofthe machine, the engagement of a blade 26 with the lever 30 raises saidlever, as shown by broken lines in Fig. 2, and the raising of said lever30 moves the blade 26 and tilts it forward until of its own weight itdrops into its forward position, (shown by Jfull lines in Fig. 2,)carrying with it the separator-bar 25. The drop-lever 30 also drops intoits normal position. It will thus be seen that .in case the operatorraises the separator-blades 26 and bar 25 for any reason and neglects tolower them they will be automatically lowered by means of the lever 30.

The advantages of my improvements will be readily appreciated by thoseskilled in the art. The plate 17, having the guide edge thereon, ispermanently attached and is not adjustable. By making a differentincline on the guide edge 17 the traverse movement of the separator-bar25 may be varied as desired.

It will be understood that the details of construction of myimprovements may be varied, if desired, and they may be applied to atwisting-frame.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a separator mechanism for a spinning or twisting frame, thecombination with a separator-bar, separator-blades thereon, and avertically-moving rod connected with said separator-bar, of avertically-extending guide to communicate during the vertical movementof the separator-bar a traverse movement to said separator-bar andseparator-blades, and also a movement in a perpendicular plane,substantially as shown and described.

2. In a separator mechanism for a spinning or twisting frame, thecombination with a separator bar, separator-blades thereon, and meansfor raising and lowering said bar, of a vertically-extending guide tocommunicate to said separator-bar, both a traverse movement and amovement in a perpendicular plane, during its vertical movement,substantially as shown and described. f

3. In a separator mechanism for a spinning or twisting frame, thecombination with the separator-bar, separator-blades thereon,avertically-extending rod having an np-and-down IIO blade adapted to bemoved into its inoperative position, of a movable arm or lever eX-tending in the path of the separator-blade in its inoperative position,and adapted to engage said blade to move it into its operative positionon the raising of the blade, substantially as shown and described.
